XPC Tools caused Shutdown

Hello,

We have an SD31P that we're using as a Server.

I installed XPC tools last week which we leave running on the desktop to control the temperature.

The temperatures usually stay at about SYSTEM=55, CPU=42, BOARD=45.

Last night, XPC caused the server to shut down. The only reference to this is in the Windows System Event Log (see below).

Does anyone know what might have caused the shutdown?

Thanks,

Richard
